[Ord. 278, 9/18/1991]
The following principles, standards and requirements will be applied by the Board of Supervisors and Planning Commission to evaluating plans for proposed subdivision or land developments. The standards and requirements outlined herein shall be considered minimum standards and requirements for the promotion of the public health, safety, morals and general welfare. Where literal compliance with the standards herein specified is clearly impractical, the Board of Supervisors may modify or adjust the standards to permit reasonable utilization of property while securing substantial conformance with the objectives of this chapter.
[Ord. 278, 9/18/1991]
1. 
Land shall be suited to the purposes for which it is to be subdivided or developed.
2. 
Land which is unsuitable for development because of hazards to life, safety, health, or property shall not be subdivided or developed until such hazards have been eliminated or unless adequate safeguards against such hazards are provided for in the subdivision or land development plan. Land included as having unsuitable characteristics would be the following:
A. 
Land subject to flooding or which has a high groundwater table.
B. 
Land which, if developed, will create or aggravate a flooding condition upon other land.
C. 
Land subject to subsidence.
D. 
Land subject to underground fires.
E. 
Land which, because of topography or means of access, is considered hazardous by the Board of Supervisors.
F. 
Land which is subject to ground pollution or contamination.
3. 
Proposed subdivisions of land developments shall be coordinated with existing nearby neighborhoods so that the community as a whole may develop harmoniously.
4. 
Proposed land uses shall conform to the Township Zoning Ordinance [Chapter 27].
[Ord. 278, 9/18/1991]
1. 
Proposed streets shall be properly related to such street plans or parts thereof as have been officially prepared and adopted by the Township and shall be coordinated with existing or proposed streets in adjoining subdivision or land developments.
2. 
Proposed streets shall further conform to such municipal, county and state road and highway plans as have been prepared, adopted or filed as prescribed by law.
3. 
Streets shall be related to the topographys so as to produce usable lots and acceptable grades.
4. 
Access shall be given to all lots and portions of the tract in the subdivision or land development and to adjacent unsubdivided territory unless the topography clearly indicates that such connection is not feasible. Streets giving such access shall be improved to the limits of the subdivision or land development and shall be improved to Township specifications. Reserve strips and landlocked areas shall not be created.
5. 
Streets shall be laid out to preserve the integrity of their design. Local access streets shall be laid out to discourage their use by through traffic, and, where possible, collector streets shall be designed for used by through traffic.
6. 
Where the proposed subdivision or land development contains or is adjacent to an existing or proposed arterial street or a highway designated as a limited-access highway by the appropriate highway authorities, provisions shall be made for marginal-access streets at a distance acceptable for the appropriate use of land between the arterial street or limited-access highway and the marginal-access streets. The Board of Supervisors may also require rear service areas, double-frontage lots, or such other treatment as will provide protection for abutting properties, reduction in the number of intersections with primary streets, and separation of local and through traffic.
7. 
Half or partial streets will not be permitted in new subdivisions or land developments. Where a half street already exists in an adjoining subdivision, the remaining half shall be provided in the proposed subdivision.
8. 
Wherever a tract to be subdivided or developed borders an existing half or partial street, the entire street shall be shown on the plan.
9. 
Dead-end streets shall be prohibited, except as stubs (with adequate turning capability) to permit future street extension into adjoining tracts, or when designed as culs-de-sac.
10. 
New reserve strips, including those controlling access to streets, shall be forbidden, except where their control is definitely placed in the Township under conditions approved by the Township Supervisors.
11. 
Where adjoining areas are not subdivided, the arrangements of streets in a proposed subdivision or land development shall be made to provide for the proper projection of streets into the unsubdivided land.
12. 
Street names shall be coordinated with existing or platted street names; and if a new street is a continuation of or is aligned with an existing or platted street, it shall bear the same name as the existing or platted street.
13. 
No street shall be laid out or opened which extends to or crosses any boundary between the Township and any other municipality, except with the specific approval of the Board of Supervisors and upon such conditions as the Board of Supervisors may impose. If the street is proposed to serve a commercial area, an industrial area or a residential area of 50 dwelling units or more, located in another municipality, the street shall not be approved unless the area is also served by a street in the other municipality and unless the relevant traffic facilities of the Township are adequate to handle the anticipated volume.
14. 
All streets shall have a uniform width throughout their respective lengths, except where otherwise required by the Board of Supervisors pursuant to § 22-504(2)(C).
[Ord. 278, 9/18/1991; as amended by Ord. 342, 9/3/1997]
1. 
Street Classification. Three functional classifications are hereby established for the streets and roads in the Township:
A. 
Arterial. This classification includes highways which provide intercounty or intermunicipal traffic of substantial volumes where the average trip lengths are usually five miles or greater. Generally, these highways should accommodate operating speeds of 35 to 55 miles per hour.
B. 
Collector. This classification is intended to include those highways which connect local access highways to arterial highways. They may serve intracounty and intramunicipal traffic. They may serve as traffic corridors connecting residential areas with industrial, shopping and other service. They may penetrate residential areas. Generally, these highways will accommodate operating speeds of 35 miles per hour.
C. 
Local Access. This classification is intended to include streets and roads that provide direct access to abutting land and connections to higher classes of roadways. Traffic volumes will be low, and travel distances generally short. These streets and roads should be designed for operating speeds of 25 miles per hour or under.
2. 
Right-of-Way Widths.
A. 
Minimum widths for each type of public street shall be as follows:
Type of Street
Right-of-Way Width
(feet)
Cartway Width
(feet)
Arterial
80 – 120
48 – 60
Collector
60
36
Local Access
50
22
B. 
Where a proposed subdivision abuts or contains an existing public street or road having a right-of-way width less than would be required if said street or road were created under this chapter, sufficient additional width for the right-of-way shall be provided and dedicated to meet the foregoing standards.
C. 
Additional right-of-way and cartway widths may be required by the Board of Supervisors to promote public safety and convenience when special conditions require it and to provide parking spaces in areas of intensive use.
3. 
Cul-de-sac Streets.
A. 
Cul-de-sac streets, whether permanent or temporary, shall be provided at the closed end with a turnaround having a minimum radius to the edge of the finished street or curbline of not less than 40 feet and a street property line radius of 50 feet.
B. 
Unless future extension is clearly impractical or undesirable, the turnaround right-of-way shall be placed adjacent to a property line, and a right-of-way of the same width as the street shall be carried to the property line in such a way as to permit future extension of the street into the adjoining tract. At such time as such a street is extended, the overage created by the turnaround outside the boundaries of the extended street shall revert in ownership to the property owners fronting on the cul-de-sac turnaround if vacated by the Township.
C. 
Commercial and industrial culs-de-sac shall be reviewed for adequacy by the Township Engineer. His recommendations will be given to the Board of Supervisors, which shall have final authority in this matter.
D. 
Permanent cul-de-sac streets shall be kept to a minimum and shall not exceed 1,000 feet in length. Because of special conditions, the Planning Commission may approve cul-de-sac streets exceeding 1,000 feet in length, in which event larger turnarounds or additional turnarounds may be required.
4. 
Street Alignment.
A. 
Whenever street lines are deflected, connection shall be made by horizontal curves.
B. 
The minimum radius at the center line for horizontal curves on arterial streets shall be 600 feet, on collector streets shall be 300 feet, and for local streets the minimum radius shall be 150 feet.
C. 
On local access streets, the minimum tangent between reverse curves shall be at least 100 feet; on collector and arterial streets, the minimum tangent shall be at least 250 feet.
D. 
Design for horizontal curves, including stopping sight distance and superelevation, shall conform to the Pennsylvania Department of Transportation Design Standards for local roads and streets.
5. 
Street Grades.
A. 
The minimum grade on all streets shall be 1%.
B. 
The maximum grade on arterial streets shall be 5%, on collector streets shall be 8% and on local access streets, 12%.
C. 
Vertical curves shall be used in changes of grade exceeding 1% and shall provide proper sight distances as specified herein above.
D. 
Design for vertical curves shall conform to the Pennsylvania Department of Transportation Design Standards for local roads and streets.
6. 
Street Intersections.
A. 
Local streets shall not intersect with collector or arterial streets on the same side at intervals of less than 600 feet as measured from center line to center line.
B. 
The distance between center lines of streets opening onto the opposite side of a proposed or existing street shall be not less than 150 feet unless the streets are directly opposite each other.
C. 
Multiple intersections involving the junction of more than two streets shall be prohibited.
D. 
Streets shall be all laid out to intersect as nearly as possible at right angles. Local streets shall not intersect collector or arterial streets at an angle of less than 75°. The intersection of two local streets shall not be at an angle of less than 60°.
E. 
Minimum curb radius at the intersection of two local streets shall be at least 25 feet, and minimum curb radius at an intersection of a local street and a collector or arterial street shall be at least 35 feet.
F. 
There shall be provided and maintained at all intersections of streets and streets and of streets and driveways clear sight triangles as defined in this section.
G. 
Intersections shall be designed so that the intersecting street proceeds on a minus 2% grade for a distance of 40 feet from the center line of the intersected street. The 2% grade and the continuing grade shall be transitioned with a vertical curve that provides adequate sight distance.
7. 
Pavement Design.
A. 
All components of the pavement structure shall be designed and constructed in accordance with Pennsylvania Department of Transportation Specifications, Form 408.
B. 
Minimum requirements for street construction in the Township shall be as specified in construction standard details adopted by resolution of the Board of Supervisors.
8. 
Alleys. Alleys are prohibited in residential developments.
[Ord. 278, 9/18/1991; as amended by Ord. 347, 3/4/1998]
1. 
Curbs.
A. 
Curbs shall be provided on all streets.
B. 
All curbs shall be depressed at intersections to sufficient width to accommodate wheelchairs. Depression shall be in line with sidewalks where provided.
C. 
Curbs may be either the six-inch-high vertical concrete type or six-inch-high, eighteen-inch-wide wedge type. The transition from one type of curb to another shall occur only at street intersections.
D. 
All vertical curbs shall be concrete with expansion joints every 20 feet and shall follow PennDOT standards where applicable.
2. 
Sidewalks and Pedestrian Walkways.
[Amended by Ord. 486, 1/4/2016]
A. 
Sidewalks shall be required in all residential subdivisions and land developments. Sidewalks or pedestrian walkways shall be required within all subdivisions and land developments proposed for nonresidential use. Sidewalks shall be provided on both sides of any new street within all subdivisions and land development plans. Sidewalks shall also be provided along any existing street within or adjacent to all commercial subdivisions or land developments, all residential subdivisions and developments of three or more residential lots, including multifamily developments and mixed-use developments; provided that, in the case of a two-lot subdivision, sidewalks shall be required if there are existing sidewalks to which the new sidewalks would connect.
B. 
If pedestrian walkways are proposed in lieu of sidewalks, or as an alternative where the location of sidewalks within the street right-of-way is not possible, they shall be located to maximize pedestrian safety and convenience and to minimize contacts with vehicular traffic, holding street crossings to a minimum. Pedestrian walkways need not meet the Township's standard specifications for sidewalks but shall be a minimum of four feet in width and constructed of asphalt or a material acceptable to the Township Engineer. Where pedestrian walkways are proposed to cross private property, an easement shall be provided that has a minimum width of 10 feet. Sidewalks along the public street frontage shall be located in the public street right-of-way or, if located on private property, shall be located in an easement with a minimum width of 10 feet. If placement of a sidewalk in the public street right-of-way is not feasible or permissible, then an alternative location across private property shall be proposed.
C. 
Sidewalks shall be constructed in accordance with the Township's Sidewalk Detail Standards. Where a sidewalk is proposed to connect to an existing sidewalk, the proposed sidewalk shall match the width of the existing sidewalk. All other sidewalks across the frontage of lots proposed for a single-family or two-family dwelling shall be a minimum of four feet in width. All sidewalks proposed across the frontage of a lot or lots on streets identified as "pedestrian corridors" on the Richland Township Overall Strategic Recreation Plan shall be five feet in width. Multipurpose walkways and bicycle paths shall be a minimum of six feet in width and constructed of asphalt or a material acceptable to the Township Engineer. All sidewalks and pedestrian walkways shall be separated from downgrade slopes that are steeper than 3h:1v by guiderail, fencing, a five-foot grading strip that is no steeper than 10h:1v, or shrubbery acceptable to the Township Engineer.
D. 
Depressed curb and ADA ramps shall be required in all such locations and instances where the Township Engineer shall determine that their use is appropriate and warranted. The dimensions for the depressed curb shall be set forth by the Township Engineer.
E. 
All other sidewalks proposed across the frontage of a lot or lots containing an existing or proposed commercial use shall be four feet in width; except where a sidewalk is proposed to connect to an existing sidewalk, the width of the proposed sidewalk shall match the existing sidewalk. Sidewalks shall be provided within a commercial land development to provide pedestrian access between the buildings and parking areas, if determined to be necessary to improve safety or pedestrian access by the Board of Supervisors, after review of a recommendation by the Planning Commission, based on the type of use proposed and the design of the site.
F. 
Maintenance responsibility for sidewalks shall be the responsibility of the landowner or shall be incorporated in homeowners' association, building owners' association or condominium documents, if such an association is proposed. A notation shall be placed in the plan specifying maintenance responsibility.
G. 
Any deviation from the regulations set forth in this section may be approved and stated in writing by the Township Board of Supervisors, after review of a recommendation by the Planning Commission and for good cause shown.
[Ord. 278, 9/18/1991]
1. 
Lots shall be laid out and graded to provide positive drainage away from buildings. The Board of Supervisors may require a grading and drainage plan for individual lots indicating a buildable area within each lot, complying with the setback requirements for which positive drainage is assured.
2. 
No person, corporation, or other entity shall block, impede the flow of, alter, construct any structure, or deposit any material or thing, or commit any act which will affect normal or flood flow in any communal stream or watercourse without having obtained prior approval form the Township or Department of Environmental Protection, whichever is applicable.
3. 
Where a subdivision or land development is traversed by a natural watercourse, there shall be provided a drainage easement or right-of-way conforming substantially with the line of such watercourse and of such width as will be adequate to preserve natural drainage.
4. 
The Township will assure that all permanent streams not under the jurisdiction of other official agencies are maintained open and free-flowing.
5. 
The subdivider or developer, and each person, corporation, or other entity which makes any surface changes, shall be required to:
A. 
Collect on-site surface runoff and dispose of it to the point of discharge into the common natural watercourse of the drainage area.
B. 
Design drainage facilities to handle runoff from upstream areas, assuming full development of those areas, based upon the Comprehensive Plan for the Township.
C. 
Design, construct, and/or install such drainage structures and facilities as are necessary to prevent erosion damage to the subdivision or land development, adjacent property and downstream property. Such structures and facilities shall satisfactorily convey such surface waters to the nearest practical street, storm drain, detention pond, or natural watercourse.
6. 
Storm sewers, culverts, and related installations shall be provided to permit unimpeded flow of natural watercourses, to drain all low points along streets, and to intercept stormwater runoff along streets at intervals reasonably related to the extent and grade of the area drained.
7. 
Storm sewers, when located in undedicated land, shall be placed within an easement not less than 20 feet wide, as approved by the Township Engineer, who may require additional width of easement as circumstances warrant.
8. 
Street drainage will not be permitted to cross intersections or the crown of the road.
A. 
Inlets shall be spaced to handle the twenty-five-year flow for the drainage areas entering the inlets, and maximum spacing of street inlets shall not exceed 600 feet.
B. 
All street inlets shall be PennDOT Type "M" or as set by standards of the Board of Supervisors. Inlet tops shall be cast-in-place reinforced concrete, precast concrete or cast iron, with flush-mounted gratings.
C. 
All culvert ends shall be provided with either reinforced concrete headwalls or pipe end sections.
D. 
Minimum pipe size shall be fifteen-inch diameter (unless as reduced by stormwater management techniques).
E. 
The following materials are acceptable for storm sewer pipe: Class III reinforced concrete (required under paving), corrugated metal (16 gauge minimum) or corrugated polyethylene (AASHTO-M252).
9. 
All springs and sump pump discharges shall be collected so as not to flow in the streets.
10. 
Stormwater roof drains shall not discharge water directly over a sidewalk. Wherever possible, roof drains shall terminate at a splatter slab or elbow fitting in the yard to discharge the rain water over lawns and shrubbery.
11. 
Stabilized outlets shall be provided for footer drains, floor drains, and downspouts.
12. 
The Soil Conservation Service TR55 "Urban Hydrology for Small Watersheds" or Rational Method shall be used as the primary means of estimating stormwater runoff.
13. 
Where the estimated runoff based upon the above methods is doubtful, several recognized methods should be studied and compared.
14. 
The minimum design criteria shall be a twenty-five-year storm. Higher frequency conditions shall be used in sensitive areas and where an overflow would endanger public or private property.
15. 
Runoff calculations must include complete hydrologic and hydraulic design and analysis of all facilities.
[Ord. 278, 9/18/1991]
1. 
Blocks and lots shall be graded to provide proper drainage away from buildings and to prevent the collection of stormwater in pools. Minimum 2% slopes away from structures shall be required.
2. 
Lot grading shall be of such design as to carry surface waters to the nearest practical street, storm drain, or natural watercourse. Where drainage swales are used to deliver surface waters away from buildings, their grade shall not be less than 1% nor more than 4%. The swales shall be sodded, planted or lined as required. A grading and draining plan shall be required for all subdivisions and land developments, except minor subdivisions.
3. 
All lots must be kept free of any debris or nuisances whatsoever.
4. 
All grading shall conform to Township Grading Ordinance [Chapter 9].
[Ord. 278, 9/18/1991]
1. 
The length, width, shape, and design of blocks shall be determined with due regard to the provision of adequate sites for buildings of the type proposed, to the land use and/or zoning requirements of the Township, the topography of the land being subdivided, and the requirements for safe and convenient vehicular and pedestrian circulation.
2. 
Unless the topography of the land being subdivided or the existing pattern of development in the immediately adjacent area shall be otherwise than herein required, the following minimum standards for the design and size of blocks and lots shall prevail where they are not in conflict with provisions of the Zoning Ordinance [Chapter 27].
A. 
Blocks shall not exceed 1600 feet in length nor be less than 500 feet in length.
B. 
Residential blocks shall generally be of sufficient depth to accommodate two tiers of lots, except where reverse-frontage lots bordering an arterial or collector streets are used, or where, due to the contour of the land or the necessary layout of the subdivision, there is insufficient depth between intersecting streets for such two-tier design.
C. 
Blocks for commercial and industrial areas may vary from the elements of design contained in this section if the nature of the use requires other treatment. In such cases, off-street parking for employees and customers shall be provided along with safe and convenient limited access to the street system. Space for off-street loading shall also be provided with limited access to the street system. Extension of streets, railroad access right-of-way, and utilities shall be provided as necessary.
D. 
Lot lines intersecting street lines shall be substantially at right angles or radial to street lines.
E. 
Lots shall, in general, front on a street which has already been dedicated to the Township or which the subdivider or developer proposes to dedicate to the Township in connection with approval of the final plan. In commercial or industrial subdivision or land developments where access is proposed to be provided by private streets within the subdivision or land development, this requirement may be waived by the Board of Supervisors.
F. 
The Township shall assign house numbers to each lot within a subdivision.
G. 
Minimum lot sizes shall be in accordance with the Township Zoning Ordinance [Chapter 27].
H. 
Remnants of land, smaller than required for a lot, shall not be permitted within any subdivision. Such remnants shall be incorporated in existing or proposed lots or dedicated to public use if acceptable to the Board of Supervisors.
I. 
Double-frontage lots are prohibited except in accordance with § 22-508(2)(B) above.
J. 
No residential lots shall be created which front upon an arterial street, as defined in § 22-504(1) herein.
[Ord. 278, 9/18/1991]
1. 
It is the policy of this Township that all subdivided lands shall have immediate access to a public street. Because of unique property configuration and location, this Township recognizes the need for limited exceptions to the foregoing general policy.
2. 
No subdivision will be approved on a private street or road if more than two lots already front on such street or road or if after subdivision more than two lots will front on such private street or road.
[Ord. 278, 9/18/1991]
1. 
In order to promote the highest environmental quality possible, the degree to which the applicant of a subdivision or land development plan has preserved existing salient natural features and land forms intrinsic to the site shall be assessed. Terms of approval of a plat may be subject to the manner in which the layout or design of the plan has preserved existing natural features, such as but not limited to trees, wooded areas and watercourses.
2. 
Open Space. Where the applicant is offering for dedication, or is required by ordinance to establish a reservation of open space or preserve an area of scenic or historic importance, a "limit of work," which will confine excavation, earthmoving procedures and other changes to the landscape, may be required to ensure preservation and prevent despoliation of the character of the area in open space.
3. 
Tree Preservation. Whenever possible, trees shall not be removed unless they are located within the proposed street right-of-way, within the proposed building area, or within utility locations and equipment access areas. In areas where trees are retained, the original grade level shall be maintained, if possible, so as not to disturb the trees.
4. 
Topsoil Preservation. All of the topsoil from areas where cuts and fills have been made should be stockpiled and redistributed uniformly after grading. All areas of the site shall be stabilized by seeding or planting on slopes of less than 10% and shall be stabilized by sodding on slopes 10% or more and planted in ground cover on slopes 20% or greater.
5. 
Landscaping. For all multifamily, apartment, office, commercial, and industrial subdivisions or land developments, a landscaping plan shall be provided and shall include sufficient plantings for the required open space, planting strips, screenings, formal gardens, shade trees and natural barriers.
6. 
Buffer Planting Requirements. Buffer yard requirements should be as specified in the Township Zoning Ordinance [Chapter 27].
7. 
Preserved Landscaping. When there is a conscientious effort to preserve the existing natural integrity and character of a site and where such preservation effectuates areas of woodland and trees comparable to required planting improvements, i.e., landscaping and buffer screening, the plan may be received in lieu of additional landscaping requirements.
8. 
Trees. The planting of trees within the street right-of-way line shall not be permitted without the consent of the Township. The planting of any trees within the private property of each residential lot shall be at the discretion of the property owner or developer.
9. 
Watercourse Protection. Where a subdivision or land development is traversed by a natural watercourse, there shall be provided a drainage easement or right-of-way conforming substantially with the line of such watercourse and of such width as will be adequate to preserve natural drainage. Such easement shall be in addition to the open space required in § 22-510(2).
[Ord. 278, 9/18/1991]
1. 
It is the policy of this Township to provide recreational facilities for all the residents of the Township pursuant to the Township Recreation Plan. Centralized facilities are preferred over local neighborhood facilities. New and additional facilities are required in direct proportion to increases in population. Developers causing increases in population by new residences must share in the cost of additional recreational facilities.
2. 
A contribution for recreation purposes of a recreational health and safety fee shall be made at the rate established, from time to time, by resolution of the Board of Supervisors, per dwelling unit, payable upon and as a condition of obtaining a building permit pursuant to the ordinances of this Township.
3. 
In addition to the above-mentioned fee, the developer may be required to provide active recreational facilities and/or open space pursuant to standards in the Zoning Ordinance [Chapter 27].
[Ord. 278, 9/18/1991]
1. 
General Purpose.
A. 
The Board of Supervisors finds that the minimization of erosion and control of sedimentation in connection with land development and subdivision are in the public interest, affecting public health, safety and welfare, and therefore those regulations governing erosion control and sedimentation control are necessary for the Township.
B. 
No changes shall be made in the contour of the land, no grading, excavating, removal or destruction to the topsoil, trees or other vegetative cover of the land shall be commenced until such time that a plan for minimizing erosion and sedimentation has been processed with and reviewed by the Township Engineer and/or the Allegheny County Soil and Water Conservation District or there has been a determination by the above entities that such plans are not necessary.
C. 
No subdivision or land development plan shall be approved unless: (1) there has been an Erosion and Sedimentation Control Plan approved by the Board of Supervisors that provides for minimizing erosion and sedimentation consistent with this section, and an improvement bond or other acceptable securities are deposited with the Township in the form of an escrow guarantee which will ensure installation and completion of the required improvements; or (2) there has been a determination by the Board of Supervisors that a plan for minimizing erosion and sedimentations is not necessary.
D. 
Where not specified in this chapter, measures used to control erosion and reduce sedimentation shall, as a minimum, meet the standards and specification of the Allegheny County Soil and Water Conservation District, the State Clean Streams Act, and shall comply with applicable regulations of the Department of Environmental Protection. The Township Engineer, or other officials as designated, shall ensure compliance with the appropriate specifications, copies of which are available from the Soil and Water Conservation District.
2. 
Performance Principles. The following measures are effective in minimizing erosion and sedimentation and shall be included where applicable in the control plan:
A. 
Stripping of vegetation, regrading, or other development shall be done in such a way that will prevent all but minor erosion.
B. 
Development plans shall preserve salient natural features, keep cut-fill operation to a minimum, and ensure conformity with topography so as to create the least erosion potential and adequately handle the volume and velocity of surface water runoff.
C. 
Whenever feasible, natural vegetation shall be retained, protected, and supplemented.
D. 
The disturbed area and the duration of exposure shall be kept to a practical minimum.
E. 
Disturbed soils shall be stabilized as quickly as practicable.
F. 
Temporary vegetation and/or mulching shall be used to protect exposed critical areas during development.
G. 
The permanent final vegetation and structural erosion control and drainage measures shall be installed as soon as practical in the development.
H. 
Sediment in the runoff water shall be trapped until the disturbed area is stabilized by the use of debris basins, sediment basins, silt traps, or similar measures.
3. 
Grading for Erosion and Other Environmental Controls. In order to provide suitable site for building and other uses, improve surface drainage, and control erosion, the following requirements shall be met:
A. 
Streets shall be improved to a mud-free or otherwise permanently passable condition as one of the first items of work done on a subdivision or development. The wearing surface shall be installed in accordance with § 22-504(7) and as approved in the final plan.
B. 
Provisions shall be made to prevent surface water from damaging the cut face of excavations or the sloping surfaces of fills, by installation of temporary or permanent drainage across or above these areas.
C. 
Fill shall be placed and compacted so as to minimize sliding or erosion of the soil.
D. 
Fills placed adjacent to watercourses shall have suitable protection against erosion during periods of flooding.
E. 
During grading operations, necessary measures for dust control will be exercised.
F. 
Grading equipment will not be allowed to enter into flowing streams, unless permitted by the Department of Environmental Protection.
4. 
Responsibility.
A. 
Whenever sedimentation damage is caused by stripping vegetation, grading or other development, it shall be the collective responsibility of the land developer and subdivider, and of the contractor, person, corporation and other entity causing such sedimentation to remove it from all adjoining surfaces, drainage systems and watercourses and to repair any damage at his expense as quickly as possible.
B. 
Maintenance of all erosion and sedimentation control facilities during the construction and development period is the responsibility of the land developer or subdivider.
C. 
It is the responsibility of any developer or subdivider, and any person, corporation, or other entity doing any act on or across a communal stream, watercourse or swale, or upon the floodplain or right-of-way, to maintain as nearly as possible in its present state the stream, watercourse, swale, floodplain or right-of-way during the pendency of the activity to return it to its original or equal condition after such activity is completed.
D. 
The subdivider or land developer shall provide and install, at his expense, in accordance with Township requirements, all drainage and erosion control improvements (temporary and permanent) shown on the erosion and sediment control plan.
5. 
Compliance with Regulations and Procedures.
A. 
The Board of Supervisors, in its consideration of all preliminary plans of subdivision and land development, shall condition its approval upon the execution of erosion and sediment control measures as contained in §§ 22-512(2) and 22-512(3) hereof.
B. 
The installation and design of the required erosion and sediment control measures shall be in accordance with standards and specifications of the Allegheny County Soil Conservation District.
6. 
Stream Channel Construction. Stream channel construction on watersheds with drainage areas in excess of 1/2 square mile, or in those cases where downstream hazards exist, will conform to criteria established by the Pennsylvania Department of Environmental Protection.
